Our pretty mixed cockerel (and two of his sisters) (11 weeks old, almost 3 months) is developing big, loooong feathers off his knees. His are the most pronounced, his sisters' curl around and bonk each other behind their legs. Is there a name for these feathers? From really far away, it looks like he's dragging his wings on the ground, but up close it's obviously coming from his thighs. His wings are normal. He's a pretty good flyer. Doesn't prevent him from doing anything: I have to giggle a little when I see him, it reminds me of a "Pilgrims Play" I saw in the 1970's, where a kid dressed as "the indian" wore a cardboard canoe cutout strapped to his thighs, so it looked like he was paddling around in a canoe. This guy looks a little bit like he's dressed in sickle blade feathers, almost like a samurai? Thank you to whomever can tell me what this is!
